Description
Technical field
The present invention relates generally to engine control technologies, more particularly, relating to engine control and the system for providing improvement.
Background technique
Gasoline and natural gas engine are for polytype vehicle provides the Main Patterns of propelling for many years.Therefore, the performance being intended to improve gasoline and natural gas engine is desired target in fields such as power efficiencies.Turbosupercharger is the improvement an example of the performance of gasoline or natural gas engine.Turbosupercharger can be considered to as a kind of gas compressor, for increasing the air quality entering motor, to produce more engine power.Therefore, turbosupercharger is a kind of air compressor utilizing internal-combustion engine to operate the exhaust gas driven produced, and it can increase the air mass flow entering internal-combustion engine or boiler, thus makes gear efficiency promote.Common in car engine, through the heat and the flow that utilize combustion gas, the horsepower that turbosupercharger can promote internal-combustion engine exports.
On gasoline and natural gas turbines supercharged engine, potential problem is to there is compressor surge when closed throttle.When closed throttle is closed from the position of substantially opening at first, this situation may be obvious especially.In this respect, when closed throttle, the air of compression will flow into closure, but due to closed throttle without any outlet.Then pressurized air decompress to pass back through turbosupercharger (causing " surge "), and this may be the exclusive path that the air of current congestion can be taked.Air pressure can be brought up to a certain degree by surge, may cause engine damage or bad noise due to turbulent flow.
In order to prevent or at least reduce the impact of compressor surge, turbosupercharged engine typically comprises the equipment of such as recycle valve.This operate with when closed throttle for allowing the air between turbosupercharger and closure to provide stream, discharged unnecessary air pressure like this, operated in safety zone to keep turbosupercharger.When using reflux valve, the suction port of turbosupercharger is got back in the usual recirculation of air, but also can be when using expulsion valve to be discharged in air.By providing the air flue of escape, the phenomenon of the damage of motor and noise and minimizing turbo lag, hysteresis phenomenon is the deceleration due to turbine, and this may cause surge.
For turbosupercharger, surge is unstable operating conditions, is therefore unhelpful.Surge is a kind of constraint physically and can not be avoided completely by turbosupercharger itself.When turbosupercharger is installed in engine/vehicle, it may enter surge region in certain operating conditions.Although recycle valve or expulsion valve can prevent surge condition effectively, reflux valve does not provide the improvement of engine power and efficiency usually, but still adds cost and the complexity of motor.Therefore, may desirable to provide a mechanism, to avoid using recycle valve.
Summary of the invention
The object of the invention is to eliminate compressor recycle valve by amendment ECU software.Method of the present invention uses measurable signal (such as atmospheric pressure, boost pressure and engine speed etc.) as input, and then lookup table is to obtain airflow requirement.This airflow requirement can be converted into the control that other relevant parameters can provide corresponding to make engine controller.The method makes turbosupercharger continuous firing in safety zone, not need the hardware added.
According to an aspect of the present invention, provide a kind of engine control, for each work cycle of motor, the method comprises: the boost pressure receiving the pressurized machine of motor; Receive engine speed; Static controling parameters look-up table is searched to select to indicate the controling parameters of airflow requirement according to engine speed and boost pressure; And the controling parameters selected by sending is to control unit of engine to control motor by the airflow requirement that this controling parameters indicates.
According to another aspect of the present invention, provide a kind of engine control system, comprising: gasoline or natural gas engine; With the turbosupercharger that this motor is combined; Control unit of engine, it comprises anti-surge control module and is configured to control at least some actuator that is associated with motor and turbosupercharger, wherein this anti-surge control module comprises: parameter pre-processing module, is configured to the boost pressure receiving turbosupercharger; Controling parameters look-up table means, comprise static controling parameters look-up table and be configured to receive engine speed, searching static controling parameters look-up table to select to indicate the controling parameters of airflow requirement according to engine speed and the boost pressure carrying out autoregressive parameter pre-processing module; With controling parameters puocessing module, be configured to selected controling parameters to be sent to control unit of engine to control motor by the airflow requirement that this controling parameters indicates.
By method of the present invention being become a part for engine control software (process), turbo charged motor can not enter " surge " region.Compared with present main stream approach, method of the present invention eliminates hardware and but has better performance.Method of the present invention can reduce system cost, reduces turbine design complexity, can better be standardized, better encapsulate in vehicle, and reduces the risk of turbine failure.Due to, utilize method of the present invention to eliminate the such as hardware such as recycle valve or expulsion valve, so only develop a software to all application, shorten the calibration operation cycle to an application, such as two months.Because eliminate risk of mechanical failure, thus there is better reliability.
